FiveHands Ransomware is a threat that appears to have been exploited by hackers via a zero-day flaw in SonicWall VPN appliances. The flaw is being exploited so that hackers can spread the FiveHands Ransomware threat, which is known to lock down an infected PC via file encryption. The encrypted files may vary and it seems that FiveHands Ransomware performs random selection of files, which may include system files where the infected PC may be rendered almost useless after the infection.
